Highly Aspherical Lenslet (HAL) and Binocular Vision (BV) Disorders [HALT X(T) Study]

Assess the effect and changes of eye misalignment (strabismus) with myopia control glasses Assess the efficacy of myopia control glasses on childhood myopia progression in children with strabismus due to the uncertainty clinicians face when prescribing myopia control glasses to these strabismic children

Studies have been done to show that spectacles, atropine eye drops, and outdoor activities have some efficacy in slowing myopia progression in children, however most of such studies exclude children with significant eye conditions such as strabismus or nystagmus to isolate the effects of myopia control treatment. In this study, we would like to investigate whether these specialized glasses can effectively slow down the progression of myopia in children with strabismus. Since strabismus can affect visual development, this study would also be able to assess the effect and changes of eye misalignment (strabismus) with myopia control glasses. The study also aims to assess the efficacy of myopia control glasses on childhood myopia progression in children with strabismus due to the uncertainty clinicians face when prescribing myopia control glasses to these strabismic children.
